Overload limiter for electric hoist

The utility model relates to the technical field of electrical control, and discloses an electric hoist overload limiter which comprises a pressure sensing box, the pressure sensing box is of a hollow box-shaped structure, a fixed pulley, a movable pulley and a pressure sensor are embedded in the pressure sensing box, and a data transmission line is fixedly connected below the pressure sensor. The lower end of the data transmission line is fixedly connected with a controller, one side of the upper end of the controller is fixedly connected with a power line, and the other end of the power line is fixedly connected with a motor junction box through a relay switch. The pulley block is adopted to replace an elastic body to transmit force, then the steel wire rope is embedded into the pulley block in the pressure sensing box, installation is completed, the data display is provided with the indicator lamps in the three colors of green, yellow and red to indicate different load capacities of the electric hoist resp
